CHURN-DASHER-OPERATING MECHANISM- SPEC IFICATION forming part of LettersPatent No. 789,763, dated May 16, 1905. Application filed January2,1904. Serial No. 187,589.

To all whom, it may concern:

Be it known that 1, JOHN F. SIMMONS, a citizen of the United States,residing at Dodge City, in the county of Ford and State of Kansas, haveinvented certain new and useful Improvements in Churn Dasher OperatingMechanism, of which the following is a speciiication.

My invention relates to an improved churndasher-operating mechanism; andmy object is to provide a mechanism of this character which may beadjusted to accommodate pails or cream-receptacles of different size.

The invention consists in a peculiarly-shaped dasher rigidly mountedupon a vertical shaft, an adjustable frame in which the upper portion ofthe dasher shaft is journaled and whereby the dasher is adjustedlaterally to accommodate pails of different diameter, and gearingarranged to rotate the dasher-shaft at a high rate of speed.

In order that the invention may be readily understood, reference willnow be made to the accompanying drawings, in which Figure 1 represents afront elevation, partly in section, of the mechanism in an operativeposition. Fig. 2 is a side elevation of the same with the dasher andshaft removed.

In carrying out the invention I employ a standard 1, U-shaped at itslower portion 2 for engagement with the edge of a table or other support3, to which it is reliably secured by a thumb-screw 4:, having anenlarged swiveled head 5 for contact with the under side of support 3.The upper end of the standard is provided with a reduced right-angularextension 6, which is adjustably engaged by a sleeve 7, adapted to belocked at any point of adjustment by a thumb-screw 8, arranged near itsinner end and adapted to contact with the right-angular portion 6.

9 is a rectangular frame comprising an upper horizontal member 9 formedintegral with the outer end of the sleeve, the latter thus forming aprojection of the frame, a lower horizontal member 9, having an opening10 at its lower inner corner, and upright side members 9 and 9connecting the two horizontal members.

11 designates a master-wheel rigidly mounted upon the inner end of astub-shaft 12, journaled in standard 1 and provided with an integralcrank 13, having a handle 14 at its opposite outturned end. Master wheel11 meshes with and drives a small pinion 15, rigidly mounted upon ahorizontal shaft 16, formed integral at its inner end with a sleeve 17,in which one end of a shaft 18 is adjustably arranged. Sleeve 17 andshaft 18 thus form sections of a telescoping shaft connecting themaster-wheel and the dasher-shaft. It is therefore possible to adjustthe dashershaft without moving the master-wheel and crank-shaft.Moreover, the intermediate connection serves as a train to produce ahigh rate of speed at the dasher. Shaft 18 is locked at any point ofadjustment in the sleeve by a thumb-screw 19 and journaled in the depending arm 9 of frame 9. It is provided at its outer end with a largerigidly-mounted bevel gear-wheel 20, extending through opening 10 andintermeshing with a small bevelgear 21, provided with a set-screw 22,Whereby it is rigidly secured to the vertical dashershaft 23, journaledat its upper portion in both the horizontal members of frame 9. Thelower end of shaft 23 is provided with a hori zontal dasher 24:,consisting of a plurality of curved blades 25.

As shown in Fig. 2, member 9 forms a guard preventing the operator orothers from coming in contact with the meshing gears on the dasher andtelescopic shafts, which are located within the rectangle formed by themembers of the frame. Member 9 is also useful as a handle in adjustingthe frame laterally on the standard.

In operation dasher 24: is adjusted laterally to the center of the pailor receptacle 26 by loosening thumb-screws 8 and 19 and shifting therectangular frame 9 laterally to the desired position, where it isreliably locked by tightening said thumb-screws. The dasher and itsshaft may be adjusted vertically by loosening set-screws 22 and 22, sothe shaft may be shiftedup or down without disturbing bevel-gear 21 andthe supporting-collar 27 None of these operations, however, affect themaster-gear and crank, which always occupy the same positions withreference to the standard. It is to be noted that the mastergearalwaysrotates in the same plane, but that the telescopic shaft can be adjustedwithout throwing the master-gear and small gear 15 out of mesh.

From the above description it is apparent that I have produced achurn-dasher-operating mechanism which is simple in construction, can bereadily adjusted, and is thoroughly effective for the purpose intended.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. In a device of the character described, the combination with astandard, a frame laterally slidable thereon, an upright dashershaftjournaled in the frame, and a small gear on said shaft; of a horizontaltelescopic shaft of which one section is mounted in the frame and theother is mounted in said standard, a large gear at one end thereofmeshing with the gear on the dasher-shaft, a small gear at the other endof the telescopic shaft, and a driving-wheel larger than all said gearsmounted on the standard and connected with the small gear on thetelescopic shaft.

2. In a device of the character described,

. the combination with a standard, a frame laterally slidable thereon,an upright dashershaft journaled in the frame, and a small gear on theshaft; of a horizontal shaft-section journaled in the frame, a largegear on the section meshing with the gear on the dasher-shaft, a secondhorizontal shaft-section journaled in the standard, a'small gear on saidsecond section,said shaft-sections being slidably connected, and adriving-wheel larger than all said gears mounted on the standard torotate in one plane only, and meshing with the gear on the secondshaft-section.

3. In a device of the character described, the combination with astandard having a right-angular extension at its upper end, a framehaving a projection telescopically connected with the right-angularextension, an upright dasher-shaft journaled in the frame, and a smallgear on the shaft; of a horizontal shaftsection journaled in the frame,a large gear on the shaft-section meshing with the gear on thedasher-shaft, a second horizontal shaft-section journaled in thestandard, a small gear on said second section, said shaft-sections beingtelescopically connected, and a drivingwheel larger than all said gearsmeshing with the gear on the second shaft-section and operating in oneplane only.

at. In a device of the character described, the combination with astandard, a drivingwheel mounted on the standard, an uprightdasher-sh-aft, a gear at the upper end thereof, a horizontal telescopicshaft, and gears thereon meshing respectively with the drivingwheel andthe gear on the dasher-shaft; of a rectangular frame comprising an upperhorizontal member slidably mounted on the standard, a lower horizontalmember, the dashershaft being journaled in both said members, an innerupright side member in which is journaled the telescopio shaft, and anouter upright side member connecting the two horizontal members andconstituting a shield, the meshing gears on the dasher and telescopicshaftbeing located within the rectangle formed by all said members.

In testimony whereof I aflix my signature in the presence of twowitnesses.

JOHN F. SIMMONS.
